Worship is giving God the glory He alone deserves. While music and worship are not the same thing, God has ordained a unique relationship between them. Both through example and command, Scripture shows us the vital role music plays in the worship of God.
Ps. 66:2 says we are to "sing the glory of His name; give to Him glorious praise." In fact, music is a gift from God designed to develop and deepen our relationship with Him.
